ADJUSTING MEANS.

Specification of Letters Patent.

Patented June 25, 1918.

Application led February 8, 1917. Serial N o. 147,485.

To all whom 'it may concern:

Be it known that I, IVALTER H. Henares, a citizen of the United States, residing at 118 12th St., in the city of Oakland, county of Alameda, and State of California, have invented certain new and useful Improvements in Adjusting Means, of which the following is a specification.

This invention relates to improved adjusting means particularly adapted for the bearings of connecting rods and like journals.

VWhile I have shown the devices applied to the ends of a connecting rod it will be understood that the same may be used wherever two parts are required to be adjustable relative to each other.

The principal objects of my invention are to provide means whereby two parts may be held in adjusted spaced relation, this relation between the parts quickly and minutely changed and the parts substantially locked in Iixed relation so that the adjustment is permanently maintained.

Another object of the invention is to so construct the device that the bearing may be taken apart and then reassembled with the parts having their former adjusted relations.

A still further object of the invention is to so arrange the parts that the nut of the holding bolt always takes the same position on the screw threads whereby locking means may be more easily used to hold it in position.

With these and other objects in view the invention consists of certain novel features of construction, combinations and arrangements of parts hereinafter described and more specifically' pointed out in the appended claims; it being understood that changes in form, proportion, size and minor details of construction, within the scope of the claims may be resorted to without departing from the spirit of the invention or sacrificing any of the advantages thereof.

iTo more fully comprehend the invention reference should 'be had to the drawings forming a part of the specifications and wherein:

Figure 1 is a view partly in end elevation and partly in section of a connecting rod showing the application of my adjusting means thereto.

Fig. 2- is a view in side elevation of the crank shaft end of the connecting rod.

Fig. 3- is a view through the center of the bearing, the cap bein removed and the adjusting bolts on one si e being shown in section.

Fig. 4- is a detailed view in perspective of the adjustingI sleeve used on the piston end of the connecting rod.

Fig. 5 is a similar view of a lock nut used in connection with the adjusting sleeve of the crank bearing.

Referring to the corresponding parts in the several views by the same numerals of reference: 1 denotes a connecting rod having the half bearing 2 formed on one end and the bearing 21 for the cross-head pin formed on the other end. The cap for half bearing 2 is denoted by 3. The members 2 and 3 are provided with circlunferential ribs l and l respectively, and the laterally extending lugs 5 and 6, which in turn are provided with holes 7 and 8 respectively. The holding bolt is denoted by 10, the head 11 whereof has a segmental portion cnt from the circumference so th'at the arc shaped portion remaining, substantially covers the seat 9 in such a manner that the bolt will not turn. The inner face of the lug 5 is recessed as shown at 12, this recess being adapted to receive the flanged head 15 of the sleeve 14. The latter has screw threads that are adapted to engage corresponding screw threads formed in the surface of opening 8. It will be noted that the radius of head 15 is greater than that of the lug 5 whereby this head will extend slightly beyond the contour of the lug enabling it to be easily turned for the purpose of adjustment. The circumferential edge of the head may be milled, knurled, or otherwise roughened to furnish a secure gripping surface.

The outer ends of lugs 6 are provided with conical recesses 21 concentric with openings 8, in which the lock nuts 17 having conical faces 22 are adapted to seat. These nuts are also provided with slits 23 extending from the smaller ends of the nuts about half way through. These nuts engage the threaded ends of sleeves 14, the latter being of sutlicient length to extend slightly through the nut. Each sleeve 14 is provided with a longitudinal Unthreaded opening through which the bolt 10 passes and this bolt is screw threaded on its outer end, as shown at 18, and provided with a vcastellated nut 19 which is firmly seated on the endof a sleeve 15 and held in this means of a cotter pin 20.

The modified form of the device used in connection with the crosshead pin consists of a sleeve 25 in threaded engagement with lug26. This sleeve is provided with an unthreaded opening 27, the outer end of which is provided with the conical 'counter-bore 28. enlargedhead 30 is formed on this end of the sleeve andaplurality of slits 31v eX,- tend from the face of, this head Partly @1011s thefsleeve l Passing through Opening 27 is a bolt Si the threaded end of which is in threadedenrgagenient with lug 35. This bolt is provided with the square 0r hexagonal. head 36 under' which'is the conical shoulder 37 closely fitted .in4 the recess, 28.

In use; adjustment is madeon the bean ing 2 by loosening lock-nut 17 and turning,

the sleeve 14 by means of its knurled head. If nut 19 is set hard against the` end of slee/,Ye 15 it will alsobe necessary to unloosen this nut. When the sleeve isu turned, cap 3 is. 'moved according to the direction of ro,- tation either to, or from the other half bea-ring. When the required adjustment is secured locknut 17 is tightened in place `and holds, the sleeve against further movement. The conical face of'this nut serves to force these surfaces into. intimate contact and also to clamp, the nut onV thebolt.

New if the bearing is taken apartY this sleeve is held in the lug 61 and in reassembling-,the parts head 15 kwill seat in the recess 12 and again position the cap as before taking apart.

Inxadjustingthe form shownon the upper end lof the connecting rod, bolt 34 is 'slackened-"of `by turning in the lug Sleeve 2,5. `is thenl turned the required amount to'. secure the necessary adjustment andV is held in this position while the `screvv34- is again tightened. This causes the lug 35 to.V

be'pulled tightly against the end of the sleeveand 'at the same timeforces the conical shoulderBT *into the recess 2 8 whereby the outer end of the sleeve 25 is spread -sufliciently that 'it lits tightly within its threaded opening. `This forcing. of the sleeve against the threaded walls vof the threaded openingfin lug 36' not only prevents 'the sleeve itself from tur-ning, but alsov prevents any movement id ue -to looseness of Contact and the internal threads of the lug.

VItwill Vthus he'seenthat I have provided an improved adjusting' means whereby accurateV and f permanent ladjustment may be Qopies of this :patent-.maybe ebtaiged for five-'cents each, by addressing the Commissioner ,efaPatents position by secured between two adjacent members and I claim as new and Wish to cover by Letters Patent z j l.
